TRIP AND STATION INDICATOR.

' 1 To all whomit may concern:

e it known that I, CUSTIs citizen of the United States, residing atCharlottesville, in the county of Albemarle and State of Virginia, haveinvented certain L. CARTER, a

- new and useful Improvements in Trip and Station Indicators, of whichthe following is a specification, reference being had therein to theaccompanying drawing.

This invention relates to station and trip indicators and one of theprincipal objects thereof is to provide means for indicating at whatstation a car or train is due at a certain time.

Another object is to provide a station indicator comprising a dialadapted to make one revolution during the run of the car, and astationary pointer for indicating the stations marked on the dial.

A further object is toprovide an indicator that may be attached to anyclock or watch.

A still further object is to provide an indicator which is durable andefficient in operation and inexpensive to manufacture.

These and other objects may be attained by means of the construction,combination and arrangement of parts as hereinafter more fully describedand claimed, and illustrated in the accompanying drawing, in which likecharacters of reference indicate like parts throughout the severalfigures, and in which,

Figure 1 is a front elevation of the indicator, and Fig. 2 is a top Viewthereof, parts eing shown in section.

My invention comprises generally a graduated and appropriately markeddial, operated by clock work to make one revolution during the course ofthe trip, whether this is fifteen minutes or several hours long; and astationary pointer to indicate the stations as they are brought oppositeit on the revolving dial.

The embodiment illustrated provides an ordinary clock casing 1, havingthe usual clock mechanism within it, but having the hands removed, andin place of the minute hand a dial 2 secured.

As is obvious the dial will make one complete revolution during an hour.The stations or stops are printed on the dial as at 3, and as manyminutes apart on the dial as it will take minutes to go from one stationto the other on schedule time. The pointer 4.- is secured between theclock face Specification of Letters Patent.

5 and the casing 1 in such a way as to overhang the dial.

onsidering two of the stations marked on the dial, let us say E. 4thst., and E. 2nd st, and supposing them to be a distance apart equal tothree minute spaces; when the graduation at 4th st., arrives oppositethe pointer, the train will be at that station, if running on schedule,and three minutes later will be at E. 2nd st., at the time E. 2nd st, isopposite the pointer, should the train be ahead of, or behind time, themotorman can ascertain how many minutes off schedule he is, and regulatethe speed of his train accordingly.

It will be seen that the device consists essentially of a rotatable dialupon which the series of stops orswitches and streets in the line aremarked in regular sequence. This dial is revolved by a regular timemechanism so that each switch or station on the dial is in due timebrought opposite a pointer fixed at the side of the dial. The stopstation or switch marked on the dial which happens to come opposite thepointer shows the point at which the car should be at that moment. Forexample, if the car was at say Fourth street when the dial shows Fifthstreet opposite the pointer, the motorman would know that he is oneblock behind time; or if he was at Sixth street he would know that he isone block ahead of time. This device enables him to keep on exactschedule at all points and times, without consulting his watch ortime-table. With this device a number of cars can be operated withoutdifliculty on single track roads, where they have to pass each other atdifferent points or sidings, as each motorman by simply noting the stopindicated by the pointer knows at once where he should be, and whetherhe is on proper time, and does not have to bother with any timeschedule. The dial is adjustable, and whether the time of the run belong or ence. But if a complete trip requires more than an hours timefor operation, without any intermediate rests, then the clock mechanismcould be arranged so that the dial will only make one complete rotationduring the time required for the trip. At the beginning of each trip themotorman should shift the dial so that the starting point designatedthereon comes opposite the pointer. Thereafter he has no further troubleas regards short makes no diiferthe time and simply knows whether he isahead or behind time by observing whether or not he is at the properpoint when the name of a designated place on the dial arrives at thepointer.

Although I have described the preferred embodiment of my invention, Ireserve, and may exercise the right to make such changes in theconstruction, combination and arrangement of parts as do not depart fromthe spirit of the invention or the scope of the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is:

1. A time controlled station and trip indicator for cars, comprising arotatable indicator or dial having the series of stops, switches andstations on the line marked thereon at predetermined intervals inaccordance with the location of such stops on the line and the timerequired or desired to traverse the distances between any two successivestops; with clock mechanism for ro tating said dial in regular time, anda stationary pointer adjacent the dial, the registry of any stop on thedial with said pointer showing the point on the line at i which the carshould be at that time.

Copies of this patent may be obtained for five cents each, by addressingthe disk bearing on 1ts face designations of the stations or pointsalong the line to be traversed by the car in regular sequence, suchdesignations being spaced apart on the dial proportionately to theirrelative localities and distances apart along the line, a pointer fixedbeside the .dial opposite which the designations on the dial aresuccessively brought as the dial revolves, and mechanism for rotatingsaid dial in regular time; whereby after the dialhas been properly setat the beginning of the trip the registry of any designated stop on thedial with said pointer will show whether the car is at the proper pointon the line at that time and whether the car is properly traversing theline; and means whereby said dial can be adjusted so as to bring theinitial or starting point indicated on the dial into register with thepointer at the beginning of the trip.

Intestimony whereof I aflix my signature in presence of two witnesses.
